Warriors of Plasm was the flagship title of Jim Shooter's Defiant Comics comic book company.
Besides the original first issue (#1) of the comic (1993), there was also a zero issue (#0) of Warriors of Plasm which was released as an insert in Previews magazine, and as a trading card set that could be put together in a binder to be read as a comic. There was also a Warriors of Plasm graphic novel titled Home for the Holidays, published in between issues #5 and #6.
Legal battle
Originally called Plasm, the title was changed after Marvel Comics threatened Defiant Comics with a lawsuit over a similarly titled series, Plasmer.
Jim Shooter changed the name to Warriors of Plasm in an attempt to avoid any further legal issues with Marvel, but Defiant Comics still wound up defending themselves in a court battle with Marvel over the name.
Defiant Comics won in court, but had spent over $300,000 in legal fees
